Self inflicted again steering box help

[mikey531]

Who has more fun than me !!! I figured out why my alternator belt was crooked while changing back to my old one. While I had it off my steering was getting a little too free so I decided to tighten the box, I have done this many times since the sixties so no big deal I had room and I could see it. Just loosen the 5/8 nut and then turn the set screw in 1/8 to 1/4 turn. What could be easier ! That shiny spot is where the adjuster used to be.
Anyone have a steering box that I can get the side plate and adjuster? GM part number is 7802644 all I need is the side plate see picture below. Thanks

I wonder if these folks could help, since they rebuild boxes.
